- This brilliantly illustrated volume brings back to life a classic mystery from an author who is too often overlooked. Bobby Blackburn is partying in New York when his grandfather Silas dies, all alone at the family manse except for a handful of servants and his cousin Katherine Perrine. There’s something suspicious here, but it’s going to take the Panamanian detective Carlos Paredes to solve this mystery of a secret room, the scene of many previous murders. What makes this edition different? It’s the many new illustrations, another offering in Absolutely Amazing eBooks’ repackaging of little-known classics.
